Product FAQs
6 answersWhich electrical panels will accept the Siemens Q260 breaker?
The Q260 is designed for standard plug-on installation in Siemens load centers and P1 panelboards. It is also the officially approved replacement for discontinued Murray load centers that originally used MP-T series breakers.
Is the Siemens Q260 a direct replacement for the Murray MP260?
Yes. Siemens phased out the Murray brand and officially lists the Type QP Q260 as the UL-listed direct replacement for the Murray Type MP MP260.
What wire sizes are compatible with the Q260, and how tight should the lugs be?
The mechanical lugs accept 8 AWG to 2/0 AWG copper or aluminum conductors. You should typically torque the terminals to 45 lb-in for 8 to 4 AWG wire, and 50 lb-in for 3 to 2/0 AWG wire. Always verify the exact torque requirements printed on the side label of the breaker prior to installation.
Is the Q260 suitable for protecting HVAC equipment?
Yes, the Q260 is HACR rated, which means it is certified for safe use with heating, air conditioning, and refrigeration systems that require a 60A circuit.
How much space does the Q260 take up in a load center?
The Q260 is a full-size, 1-inch per pole breaker. Because it is a 2-pole device, it requires two adjacent 1-inch slots, taking up 2 inches of total width on the panel bus.
Can I use aluminum wire with the Q260 breaker?
Yes, the mechanical lugs on the Q260 are AL/CU rated, meaning they are certified for safe termination of both solid or stranded copper and aluminum wire within the approved 8 AWG to 2/0 AWG range.
